Unified eCOA
That Patients Finish.
Delve Health combines modern eCOA with real-time QC, wearable data, and human support to keep diaries complete, reduce deviations, and eliminate site troubleshooting burden.
92–98% diary completion · 2–3× retention uplift.
eCOA Built for Real-World Research
Clinical outcomes fail when patients miss diaries, devices break, or sites can’t support troubleshooting. Delve Health solves this by blending modern eCOA, wearable-driven insights, and human engagement into one unified ecosystem.
Data becomes more reliable. Patients stay supported. Sites stay unburdened. Sponsors get cleaner evidence with fewer deviations and faster readouts.
- Multilingual, global-ready eCOA + ePRO
- Real-time QC and deviation prevention
- BYOD or fully provisioned devices with SIM
- Wearables + ePRO harmonized to create digital endpoints
- Concierge support in 120+ languages
The Three Pillars of Modern eCOA
High-performing eCOA isn’t just digital forms. It’s the intersection of patient experience,
protocol rigor, and continuous support designed to work in the real world.
Patient-Centric, Multilingual, Accessible
Mobile-first assessments with adaptive UX, multimedia prompts, and multilingual support.
Digital Measures
Validated, fit-for-purpose measures from wearables and sensors, ready for regulators.
Concierge-as-a-Service™
Human teams who own the work of keeping participants active, informed, and on schedule.
A Flexible, Powerful Form Builder
Build protocol-aligned instruments in minutes — no custom development needed. StudyPal’s authoring tools let research teams design, test, validate, and deploy assessments faster than traditional eCOA vendors.
- PRO, ClinRO, ObsRO, PerfRO support
- Full branching, scoring, conditional logic
- Audio, video, and image capture inside forms
- Sequential forms and multi-part workflows
- Visit windows auto-adjusted to patient behavior
- Real-time edit checks and version control
All forms stay aligned with regulatory expectations — including FDA, EMA, and ICH E6(R3) guidance.
Subjective + Objective Data in One Place
Wearables provide objective data; ePRO captures subjective experience. Delve Health merges the two — enabling richer endpoints, early signal detection, and context around patient behavior.
- FDA-aligned digital endpoints
- Activity, HR, HRV, SpO₂, sleep, respiratory data
- Correlated with symptom diaries, ClinRO, and visit forms
- Real-time biomarker trends and alerts
This is the future of evidence generation: signals + symptoms → complete insight.
Where Other eCOA Vendors Stop, Humans Take Over
Software alone cannot fix missed diaries, low tech literacy, battery issues, or sync failures. Delve’s Concierge-as-a-Service™ becomes the operational engine behind your study.
- Follow-up on missed entries in real time
- Multilingual patient coaching & troubleshooting
- Direct support for sites during busy visit days
- Reduced deviations, higher compliance
- Proactive intervention when wearable or app issues occur
It’s not just eCOA — it’s eCOA with a human safety net.
